Xander the Poison King (died 431 BC) was a Greek mercenary during the Peloponnesian War.

Biography
As a child, Xander was intrigued by how poison could consume even the strongest men. He then dedicated his life to mastering the art of poisoning, not necessarily to kill the strongest, but the ones who were not good enough to take on the challenge. In 431 BC, he was hired to hunt down and kill the rival mercenary Kassandra, tracking her down to the Mt. Pentelikos Marble Quarry. Kassandra slew Xander after a short battle.
